This invention relates to a signal device, the general object of the invention being to provide a set of signals simulating those used for directing and controlling traffic so that the device can be used in teaching children the knowledge of traffic signals and safety rules, the device also being capable of use for controlling trafiic 'on highways which are under repair.

This invention alsoconsists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Fig. l is a view showing the invention applied to a desk.

Fig. 2 is a front view of the signal.

Fig. 3 is a section on line 3-3 of Fig. 2.

Fig. 4 is a bottom plan view of Fig. 2.

Fig. 5 is a diagrammatic view of the circuit.

In these drawings, the numeral I indicates a tubular upright having a base board 2 connected to an upper part, preferably by cutting away the front portion of the tube so that a portion of the board will fit in the cut away portion, as shown in Fig. 3, the board being connected to the upper part of the tube by bolts or rivets 3. A vertical row of casings 4 is attached to the base board by such rivets or otherwise and the front of each casing is open and supports a transparent member 5, these transparent members being of different color and of colors similar to those being used in traffic signals in use in the community in which the device is used. An electric lamp 6 is arranged in each casing, the socket I of which being suitably attached to the rear wall of the casing and conductors 8 lead from the sockets into the tubular upright I and to a switch block 9 which contains the switches I0, one for each lamp. The circuit is shown diagrammatically in Fig. 5.

The lower end of the tubular member I is split and a cross piece I I passes through the split por- 6 tion and is fastened to the lower part of the tubular member as shown at I2.

When the device is in use for teaching children or other persons in a room, the device can be placed on a desk as shown in Fig. 1 with the 10 switch board resting on the desk and one drawer can be partly pulled out with the split portion of the upright fitting over a portion of the desk and the cross piece resting on an edge part of the drawer as shown in Fig. 1. If the desk is provided with an upright back-board on the top, the device can be placed on this board or if desired, the upright with the lamps can be attached to a wall. When the device is used as temporary signal, when a road is being repaired, the upright may be placed on a wooden horse or the like and used for controlling traffic over said part of the highway. When used in a classroom or the like, it will familiarize children with the signals used for controlling traffic so that the children will 5 secure a knowledge of such signals and safety rules.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

I claim:

In a device of the class described, an upright having a vertical slot in its lower part extending through its lower end and a cross piece passing through the slot and having its lower edge spaced from the lower end of the upright, and means for connecting the cross piece with the upright.
